proFIL 4201 - AIS TRX / DSC duplex filter 160MHz-162MHz / DSC ch70

The proFIL 4201 is a high-performance duplex filter designed for integrating AIS and DSC systems using a single VHF antenna. It features high isolation technology, effectively separating AIS and DSC channels to prevent interference, which is crucial for maintaining reliable communication at sea. The filter's low insertion loss ensures that signal strength is preserved, enhancing the performance of both systems. Its compact, robust design allows for easy installation on vessels, reducing the need for additional antennas and cabling. Constructed from painted aluminium, it is built to withstand the challenging conditions of marine environments, making it a reliable choice for vessel operators.
